Dual ameliorative effects of Ningdong granule on dopamine in rat models of Tourette's syndrome.

Zhang F, Li A - Sci Rep (2015)

Bottom Line: Dopamine (DA) is a key neuromodulator in the brain that supports motor and cognitive functions.By using high-performance liquid chromatography (HPLC), we found that long-term administration of NDG could, at least partially, restore the striatal dopamine alterations, either by increasing them after IDPN treatment or by decreasing them after Apo treatment.Taken together, our data indicated that NDG could ameliorate the abnormal striatal DA content dually, and the unique therapeutic property may be meaningful for the treatment of TS.

ABSTRACT
Dopamine (DA) is a key neuromodulator in the brain that supports motor and cognitive functions. Here, we use apomorphine (Apo) and 3,3'-iminodipropionitrile (IDPN) to develop two rat models of Tourette's syndrome (TS), a common neuropsychiatric disorder characterized by stereotyped repetitive involuntary tics. The models enabled the assessment of unique ameliorative effects of Ningdong granule (NDG), a traditional Chinese medicine (TCM) preparation dedicated to the treatment of TS, on the striatal DA content of rats. By using high-performance liquid chromatography (HPLC), we found that long-term administration of NDG could, at least partially, restore the striatal dopamine alterations, either by increasing them after IDPN treatment or by decreasing them after Apo treatment. Taken together, our data indicated that NDG could ameliorate the abnormal striatal DA content dually, and the unique therapeutic property may be meaningful for the treatment of TS.

Mentions: The effects of NDG on the striatal DA content of the rats are shown in Figure 2. The ANOVA revealed significant effects for both groups (Apo: F3,36 = 30.79, p < 0.01; IDPN: F3,36 = 16.07, p < 0.01). Our data revealed that Apo and IDPN produced completely opposite effects on striatal DA content of the rats: manipulations of Apo significantly increased the DA concentration in striatum (p < 0.01), while the IDPN exposures were associated with marked decrease in DA content (p < 0.01), both compared with the same control rats.
